The area is still officially considered a construction site, which is why entry is prohibited — anyone who dares to do so does so at their own risk. However, seeing the former magnificent building from the outside is an experience in itself. Furthermore, according to „Troj Miasto”, there is now hope that Lapalice Castle could eventually be completed in the not-too-distant future: According to reports, the city council has approved the development of ideas for future use, almost 40 years after the dream began to take shape. Kazimierczak is said to have already expressed interest in a collaboration.

Kazimierczak has since submitted multiple applications to be allowed to continue building on his castle, but so far they have all been rejected. And yet, the unfinished building, solely due to its incredible size, has become a tourist attraction that thousands of people visit every year. Among locals, the place is just as popular for picnicking against the impressive backdrop.

The Polish artist Piotr Kazimierczak has a vision. That was in the early 80s. The vision can be described as ambitious – or simply megalomaniacal. As the local news site „Troj Miasto” reports, Kazimierczak wants to build himself a home. But not just any house, but a castle. He seems to have enough money for it, he became rich through the sale and maintenance of church furniture.

This impressive church, built by the Carthusian monks between 1383 and 1405, is unmissable! It is the best-preserved Carthusian church in Poland. Inside, it boasts magnificent historical furnishings: an altar from 1444, Baroque choir stalls, and chancel walls upholstered in Flemish cordovan. And the exterior? The roof is shaped like a coffin!

The beautiful sanctuary in Sianów, built in 1816, is a venerated statue of Mary and Child, made of linden wood, and has been an object of homage for the Kashubian people since the Middle Ages. It's a beautiful and peaceful place.

A wonderfully calming place after miles of pedaling. Delicious teas can be sampled in a pavilion nestled among beautiful plants from around the world.

An extraordinary example of megalomania. Of course, illegal entry.
